10 Claims.

The object of my invention is to improve the type of disk plows adapted to break land preparatory to subsequent tillage, whereby I am enabled to provide disk assemblages of an improved and l highly durable character capable of being readily adjusted to varying degrees of angularity as conditions may require, as will hereinafter more fully appear.

In the accompanying drawings, forming part hereof, Figure 1 is a fragmentary plan View of a disk plow equipped with my improved disk assemblage; Figs. 2 and 3, detail views of the disk supporting standard employed and showing the same in varying positions in relation to the beam; Fig. 4, a detail sectional view taken on the dotted line 4-4 in Fig. 3; Fig. 5, a perspective view of the adjusting device for positioning the standards; Fig. 6, an elevation of fragmentary portions of the standard and disk; Fig. 7, a transg9 verse section taken on the dotted line 77 in Fig. 6; and Fig. 8 is a detail section taken on the dotted line 8-8 in Fig. 6.

In said drawings the numeral 5 indicates the frame, 6 the beam, '7 the trailing wheel, and 8 the adjusting wheel, all of which plow parts and their connections may be of any desired character.

As the disk assemblages are counterparts in all respects it will only be necessary herein to specifi- 30 cally describe one of the same, which comprises a bracket 10 having a vertical web orwall 11 and an angled web 12 forming a channel 13, and having bolt receiving members 14 and a boss 15.for securing a guard or binder 16, connected thereto by bolts 17 for clamping the bracket and standard, said bracket also including a slot 18 for a purpose to appear, and'which bracket is secured to the plow-beam 6 by bolts 19.

The standard 20 comprises a bar or arm having its lower end 21 turned at right angles to form an axle, threaded at 22, to receive and nonrotatably secure a base-plate 24 having ball races 26, 27 in its opposite faces. The disk assemblage includes a back-plate having a ball race 26 5 registering with the race 26 in plate 24, and, when assembling the disk parts to be mounted on axle 21 the back-plate is placed on hub 25 of plate 24, a lubricating washer 31 being interposed therebetween, and balls 28 inserted in the race between the plates. A disk bearing 32 is then placed against base-plate 24, with balls 28' inserted in the race therebetween. The disk assembly is mounted on the threaded axle 22 and bearing 32 rotated until a pin-hole 29 therein registers with a similar hole in the base-plate 24, when a pin (not shown) is inserted in the holes, so that the parts 24, 30 and 32 become a unit and together are tightly secured to the axle by the threaded engagement of hub 25 with said axle. Bolts 33 are then inserted through the bearing and back-plate to secure the same with the base-plate in assembled relation, while the disk 34 is secured to said bearing by bolts 35 after the locking-pin has been removed, the structure thus being a unit, which is installed upon the standard 20, as indicated, by threading the base-plate onto the screw-threaded portion of axle 21. A series of adjusting screws 36 are employed for regulating the distance between the base-plate 24 and back-plate 30 and also the bearing 32, which screws are inserted through the back-plate and contact with bearing 32 to space said disk elements as may be desired. It will thus be seen that the base-plate 24, back-plate 30 and disk bearing 32 are provided with ball-races in which a series of balls 28, 28 are inserted whereby a minimum of friction is present upon rotation of the back-plate and disk-bearing about the base-plate, and that by adjusting the setscrews 36 the relation between said parts may be regulated as desired; and it will also be understood that the washer 31 and the shouldered for- 'mation 32 of the bearing 32 and the formation 30' of the back-plate 30 exclude foreign matter from entering between the rotating parts and g5 prevent leakage of lubricant, and that all of said partsincluding the standard are held in compact assembled relation by the devices described, resulting in a stable and durable disk equipment for the purpose.

When connecting the disk assemblage with the beam 6 the standard 20 is inserted in the channel 13 of bracket 10, and in order to vertically position said standard the latter is placed, as shown in Fig. 3, against the vertical web 11, leaving an angular space at the opposite side adjacent the web 12. For fixedly securing the parts in the position stated I employ an adjusting device comprising a body portion 40 having an opening 41 therethrough and wedging members or legs of any desired form, as 42, 43, 44, Fig. 5, the leg 43 being thicker than 44, and the latter thicker than leg 42, for the purpose to appear. In securing the standard in vertical position, Fig. 3, the leg 43 is inserted in the space 13 alongside web 12 and at 05 the same time leg 42 is slipped over the top of the standard, while leg 44 enters a hole 45 therein, in which position of the device standard 20 is prevented from lateral play, and the parts are then fixedly secured by bolt 46 passing through the opening 41 of the adjusting device and the slot 18 in the bracket 10. When it is desired to adjust the disk 35 to its maximum angled position, the adjusting device is removed, the standard then placed as indicated in Fig. 2, when the device is applied in the reverse direction to that shown in Fig. 3 so that its thickest wedge or leg 43 will be inserted in the angular space 13 between the standard and the web 11, Fig. 2, leg 44 passing over the top of the standard and'leg 42 at the same time being inserted in hole 45.

Lesser degrees of angularity of the standard may be obtained by placing the leg 43 in slot 45 and locating legs 42 and 44 accordingly, and also by placing leg 43 above the standard and the other legs accordingly and one of which serves as a wedge, so that by this simple adjustment I am enabled to set the standard in four different positions to angle the disk 35 as desired, and in each such position bolt 46 will occupy the proper relative position to bracket 10 by the elongated slot 18 whereby it may be located wherever necessary.

It will be understood also that after each such adjustment the bracket 10 and standard 20 are further fixedly secured by the guard 16, which is shown in fragment and in the position indicated in Figs. 2 and 3, and connect'the same to the bracket by bolts 1"], by which means and the adjusting device thestandard is immovably secured without the necessity of providing holes therein at its greateststraining point.
